OPERATING DEVICE AND METHOD FOR OPERATING A ROTATION-RATE SENSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18484697 titled 'OPERATING DEVICE AND METHOD FOR OPERATING A ROTATION-RATE SENSOR

Simplified Explanation

The patent application describes an operating device for a rotation-rate sensor that utilizes mechanical amplification of deflection oscillatory motion and/or a phase shift of the deflection oscillatory motion relative to a harmonic drive oscillation of a seismic mass. This is achieved by considering drive frequencies variable with respect to the characteristic drive frequency of the harmonic drive oscillation and detection frequencies variable with respect to the characteristic detection frequency of the deflection oscillatory motion caused by a Coriolis force.

• Mechanical amplification and phase shift of deflection oscillatory motion

Original Abstract Submitted

An operating device for a rotation-rate sensor. A mechanical amplification of a deflection oscillatory motion and/or a phase shift of the deflection oscillatory motion relative to a harmonic drive oscillation of a seismic mass can be determined using an electronic apparatus of the operating device by taking into account at least one drive frequency variable with respect to a characteristic drive frequency of the harmonic drive oscillation of the seismic mass of the rotation-rate sensor and by also taking into account at least one detection frequency variable, which is provided by the operating device itself to the operating device, with respect to a characteristic detection frequency of the deflection oscillatory motion, caused by a Coriolis force, of the seismic mass put into the harmonic drive oscillation or with respect to a difference between the characteristic drive frequency and the characteristic detection frequency.
